Hi,

The Q is related to Modifiers...

WHO is "without adequate amounts of sleep",it is the PEOPLE and not their skills....So A,B and C are out..

Left with D and E, the point is between adequate amounts of sleep and the adequate amount of sleep...We are not talking of some specific thing, so THE is not required.

The first thing I notice is the use of noun modifiers at the beginning of both (A) and (B):

Quote:

A. Without adequate amounts of sleep, people's newly acquired skills and alsoB. Without the adequate amount of sleep they need, people's newly acquired skills and even

Without adequate amounts of sleep,..." - logically, this modifier should describe people. But in (A), there are no "people", really: since "people's" is possessive, the opening modifier describes "people's skills." And it wouldn't make sense to talk about the sleep habits of "people's skills." Eliminate (A).

(B) is even worse. We still have the same problem with the opening noun modifier, which technically describes skills and information rather than people. We also have a subject pronoun ("they") trying to refer to a possessive noun ("people's"), and this is not allowed (for more on possessive pronouns, check out this thread). Finally, the addition of "they need" is redundant, since an "adequate amount" is, by definition, the amount needed. Eliminate (B).

In (C), we once again have a subject pronoun ("they") trying to refer to a possessive noun ("people's"). As written, "they" seems to refer to "skills" and "information", and this is illogical.

(D) and (E) are pretty similar, but we've already established that "adequate" + "they need", as used in choice (E), is redundant. In addition, the word "also" is unnecessary in (E). For example, I would say, "Mike likes to drink beer and wine", not "Mike likes to drink beer and also wine." (D) doesn't have any redundancy issues ("even" is correctly used as an adverb for emphasis), so that's our answer.

Can you also throw some light on the usage of 'amount of something' and 'amounts of something'. Do they mean the same? Under what scenarios can the usage of 'amounts of' be right and wrong?

Interesting question, Vyshak. I don't really think it's an issue at all -- they don't really differ substantially in meaning, and I can't really think of a case when one would be correct and another would be incorrect. Honestly, the singular version ("amount of sleep") sounds better to me, but the GMAT clearly has no problem with "amounts of sleep"... and as usual, the GMAT really doesn't care what I think sounds better.

So I wouldn't worry about it. It's never the deciding factor in any official questions.
